WILLIAM HESTON, OF MOUNT UNION, ASSIGNOR'OF ONE-HALF TO JAMES E.INGERSOLL, on BEDFORD, OHIO.

VAPOR-BURNER.

SPECIFICATION forming part of Letters Patent No. 270,587, dated January16, 1883.

Application filed October 10, 1882. (No model.)

To all whom it may concern:

Be it known that 1, WILLIAM HEsToN, of ivlount Union, in the county ofStark and State of Ohio, have invented a certain new and 1mprovedVapor-Burner; and I do hereby declare that the following is a full,clear, and complete description thereof.

This improvement relates to a vapor-burner, the nature of which consistsof double perfo- IO rated caps, one of which is stationary andthe othermovable for the purpose of regulating the flame-jets, and to cause asmall jet to continue burning to'avoitl the trouble and-delay inrelighting.

The improvement also relates to the means employed for generating thevapor from the oil for combustion in the dome.

For a more full and complete description of the said improvementsreference will be had to the following specification, and to the annexeddrawings, making a part of the same, in which Figure l is a View of avertical section in part of the vapor-burner; Fig. 2, a top view. Figs.3, 4, and 5 are views of the perforated caps detached.

Like letters of reference refer to like parts in the several views.

The combustion-chamber A, Fig. 1, is in- 0 closed by two perforatedcaps, B (J, of which B is the inside stationary cap and O the outsidemovable one. The interior cap is adjusted to the base or floor D of thecombustionchamber, so as to fit on the inside of the flange E, and isprevented from turning by means of the lug or pin F, which projects fromthe base into a slot, G, in the lower edge of the cap, as seen in Figs.1 and 4. This pin and slot prevent the cap from turning; but it may bereadily removed and replaced, as occasion may require. The exterior cap,O, fits down over the interior one, and closes up the opening in theupper part or top of the interior one. The

lower edge of the exterior cap, 0, rests upon 5 the flange E of the baseD, while the interior cap is on the inside of the flange E, which flangeprevents the insidecap from moving laterally, and thereby the exteriorcap is also prevented from moving laterally, but is free to turnhorizontally, so as to open or close the perforations in the caps,respectively. The exterior cap is permitted to turn only a certaindistance sufficient to regulate the gas-jet from the perforations a.This is attained by means of lug H, projecting from the upper edge ofthe 5 flange E into the elongated slot or opening I in the lower edge ofthe exterior cap. The shoulders at each end of the opening determine thedistance of the horizontal rotation of the cap, as lug H forms a stopfor the shoulders. When full jet-flames are required the exterior cap isturned in the direction of the arrow, Fig. 3, until the shoulder J isbrought in contact with lug H, or nearly so, which will close theopenings K and L and open the perforations at in the respective caps.The volume of flame-jets may be more or less reduced by turning theexterior cap in a reverse direction of the arrow, which will close upthe perforations a, as required, for less heat. This closing of theperforations is due to the blank spaces of the exterior cap coveringover the perforations of the interior cap. This opening and coveringofthe perforations in the interior cap causes more or less volume of flameto issue from the combustion-chamber A. On turning the exterior cap sothat the shoulder N will be in close proximity to the lug H, theperforations .of the interior cap will be closed over by the blankspaces between the perforations of the exterior 8o cap. In this positionthe openings K and L will coincide with each other and will have aflame-jet issue from the chamber A through them, and impinging on theface M of thegenerating-chamberM; but as the volume offlame from thesejoint openings is much less than from the perforations of the caps therewill be less heat imparted to the chamber M. Hence less gas is generatedfrom the oil therein, but sufficient will be evolved to produce a lowconstant flame, enough at any time to cause full jets to issue from theperforations on turning the exterior in the direction of the arrow, soas to increase the heat upon the generatingchamber from the openings. Inthis way, after the firstlighting of the burner by means of the oil-cup0, it need not be resorted to, as the burner may be fully inflamed fromthe result- L of the caps.

full-open relation with each other, so that the ant effect of the jetfrom thejoint openings K V hen the perforations are in maximum volume ofjets is attained, the perforation 0, Figs. 3 and 5, will then coincidewith the opening L in the interior cap, Figs. 1 and 4, to cause a jet topass from the combustion.- chamber through this space, which otherwisewould be blank, and to be impinged upon the generating-chamber. It willbe noted that the opening L will at all times be in the same position,directly opposite the upper part of the generating-chain her, as seen inFig. 1.

The turning of the exterior cap is so regulated or determined by the lugH, in connection with the slot I and the shoulders J N, that the cap canonly be turned a given distance, and when moved to the position seen inFig. 3 the perforations a are closed and the openings K L made tocoincide, so that a light low flame ensues therefrom, and on turning thecap 0 in the direction of the arrow the openings K L are closed and theperforations opened accordingly.

To the cap 0 is connected a handle, P, for turning it.

Connected with the base or floor of the chamher A is a conducting-tube,R,which is in open relation with the needle-valve mechanism S at itslower end, the upper end opening into the combustion-chamber, as seen inFig. 1. The tube It is supported in a bracket, T, attached to thegenerating-chamber M, Figs. 1 and 2, by which the combustion-chamber isheld in position. To the lower end of the generating-chamber is attacheda supply-pipe, U, leading to the oil-supply tank. (Not shown, as it maybe same as ordinarily used for this purpose.) In the interior of thegeneratingchamberis a "apor-pipe, Q, closed at the lower end and open attop into the generatingchamher, as seen at Q. This vapor-pipe forms apart of the said chamber M.

Extendingfrom the vapor-pipe Q, and in open relation therewith, is abranch pipe, V, which connects with the needle-valve pipe W,in which isfitted the needle-valve, the stem b thereof being provided with a handlefor operating in in the usual way.

Directly under the generating-chamber and attached to the pipe U is anoil-cup, 0, Figs. 1 and 2, into which oil is conveyed from the lowerpart of the generating-chamber M by means of the valve-cock d, whichadmits of more or less oil passing from the chamber M into the cup, asmay be required. The supply may be stopped entirely by closing thevalve-cock, the stem of which is seen at f, Figs. 1 and 2. 0n the oilbeing conveyed to the generating-chamber M and the cup supplied,

as before stated, the ignition of the oil in the cup will convey heat tothe generating-chamber, causing generation of vapor from the oil, whichwill pass through the pipes Q V to the needle-valve pipe or chamber,thence through the conductor B into the combustion-chamber, from whichchamber it issues through the perforations and openings before setforth. A portion of the flamefrom the chamber-A passes throughperforations or openings adjoining the upper part of thegenerating-chain her, thereby supplying the required heat for theconstant generation of the gas or vapor so long as the supply of oil iscontinued. The upper end of the pipe Q is in close proximity, at Q, tothe upper end of the generating-chamber M, by which regurgitation of theoil through the pipes on igniting the burner is arrested, as the rapidgeneration of gaseous vapor above the oil in the chamber will havesutiicientpressure above the oil to resist the ebullition of the oilengendered by the heat from the cup 0 when ignited, and therebypreventing its passage through the pipes to the combustionchamber.

What I claim. as my invention, and desire to secure by Letters Patent,is-

1. In vapor-burners, the two perforated caps B (3,.arranged one withinthe other, the interior one being stationary and the exterior onemovable therein, and provided with openings K L, slot l, and lug H, incombination with the pipe 1t and needle-valve mechanism, substantiallyas described, and for the purpose set forth.

2. In vapor-burners, an improvement consisting of double perforated capsB 0, provided with openings K L, the interior cap being stationary andadjusted to the floor of the combustion-chainber within the flange E,andI00 the exterior cap, 0, inelosing the said cap B and turning upon thesame, in combination with the pipe It, generating-chamber, andneedlevalve mechanism, substantially in themanner as described, and forthe purpose specified.

3. In vapor-burners,thecombustionchamber having a stationary and movablecap, slot I, and pin H, with a pipe extending from the needle-valvemechanism into the interior of said chamber, in combination with thebracket 1 10 T, generating-chamber, openings K L, and pipes Q V,arranged substantially as and for the purpose set forth.

In testimony whereof I aflix my signature in presence of two witnesses.
